Effets masqués en analyse prédictive / Masked effects in predictive analysis

Bascoul, Ganaël 27 June 2013 (has links)
L’objectif de cette thèse consiste en l’élaboration de deux méthodologies visant à révéler des effets jusqu’alors masqués en modélisation décisionnelle. Dans la première partie, nous cherchons à mettre en œuvre une méthode d’analyse locale des critères de choix dans un contexte de choix binaires. Dans une seconde partie, nous mettons en avant les effets de génération dans l’étude des comportements de choix. Dans les deux parties, notre démarche de recherche combine de nouveaux outils d’analyse prédictive (Support Vector Machines, FANOVA, PLS) aux outils traditionnels de statistique inférentielle, afin d’enrichir les résultats habituels par des informations complémentaires sur les effets masqués que constituent les effets locaux dans les fonctions de choix binaires, et les effets de génération dans l’analyse temporelle des comportement de choix. Les méthodologies proposées, respectivement nommées AEL et APC-PLS, sont appliquées sur des cas réels, afin d’en illustrer le fonctionnement et la pertinence. / The objective of this thesis is the development of two methodologies to reveal previously hidden effects in decision modeling. In the first part, we try to implement a method of local analysis in order to select criteria in the context of binary choices. In a second part, we highlight the effects of generations in the study of consumer behavior. In both parts, our research approach combines new predictive analytical tools (such as Support Vector Machines, FANOVA, PLS) to traditional tools of inferential statistics, to enrich the usual results by additional on the masked effects, which are the local effects in the binary choice functions, and the effects of generation in temporal choice behavior analysis.The proposed methodologies, respectively named AEL and APC- PLS are both applied to real cases in order to illustrate their operation and relevance.

Steinerovská barvení kubických grafů / Steiner coloring of cubic graphs

Tlustá, Stanislava January 2017 (has links)
This thesis is dedicated to the coloring of cubic graphs. It summarizes the knowledge we have about so called Steiner coloring, which is an edge-coloring such that the colors incident with one vertex form a triple of some partial Steiner system. The main objects of interest are the projective and affine systems. Afterwards the sufficient condition for universality of the system is stated and it is observed, that all other transitive Steiner triple systems satisfy it. This thesis also contains methods of construction of the coloring for the Fano plane, for the affine system Z3 3 and for the universal system created as a product of the Fano plane and the trivial system (F7 S⊠ 3). Finally an algorithm usable for the rest of the systems and graphs with bounded treewidth is presented.
